I found something at a thrift store I can not identify. They are sewing machine cams in a blue metal box (5 X 6.5 X 2"H). Inside are 3 rolls of 20 cams for a sewing machine. On the front of the metal tin it says, Pattern Discs. The discs measure about 2" in diameter and about one inch high.

Would any of you know what Sewing Machine these would fit?
Sorry, I can't attach a picture for you.

Singer, Kenmore, Necchi...all have sewing machine models that use cams. If you can't post us a picture maybe you could use http://images.google.com/ and search "sewing machine cams" to find an image of ones like yours. You could at least identify what sewing machine brand they are.
